According to the artist, his art is dedicated to the elevation of the aesthetic taste of the Mexican working class. Rivera aimed towards -and achieved, becoming a revolutionary artist. His mission was to produce works of art with a humanistic content and literal in their purpose of critique. He wanted to please and illustrate the lay public.
In the 1930s Rivera expressed his personal beliefs about painting as well as the nationalistic characteristics of Mexican people through the depiction of images that embedded indigenous sensibilities as well as the individual character of the figures depicted. This important period in Rivera's career was marked by the exaltation of the Mexican campesino. His paintings recognized aesthetic practices beyond European styles and captured the proper ambiance and features of the people of his country.
Vendedora de puercos represents in the artist's high style, a caretaker of pigs. Like most of Rivera's depictions of the working indigenous classes, his realism is respectful and serene, with a touch of nostalgia that emanates from the fine use of color, line and form.
